Effects of dynamic screening on the electrical conductivity of fully ionized, nondegenerate hydrogen plasma

Abstract

The electrical conductivity of fully ionized, nondegenerate hydrogen plasma is expressed within the Zubarev method by equilibrium correlation functions. Using the Green’s function technique, the Lenard–Balescu–Gurnsey collision integral of a generalized Boltzmann equation is derived that accounts for the effects of dynamic screening. Applying the usual random phase approximation, numerical results for the collision integral and the electrical conductivity are compared with the case of static screening (ω=0) and the long-wavelength limit (q→0) for the dielectric function Ε(q,ω). Effective low-density expansions are given for the collision integrals as well as for the electrical conductivity that are applicable for a wide range of density and temperature.
